Map of Bettles area

Bettles station history

Located on Koyukuk River south of Brooks Range and 4 miles east of Alatna
Hills. Current coordinates 66 degrees 55' N, 151 degrees 31' W, elevation
644 feet. Station opened 1944 at 66 degrees 54' N, 151 degrees 43' W, 848'
elevation but moved 5 miles NE and 182' lower in 1951. (Probably from old
Bettles village on map to Bettles Airport, see map.)
An additional elevation change of 22' down was reported in 1968, but with
no corresponding horizontal change - suspicious. Located in CAA/FAA Control
buildings until 12/3/69; became flight service station 12/3/69.

Midnight observations throughout, so only possible time correction needed
would be for change from midnight to 11 pm with time zone change 10/31/83.
Observer some USWS, mostly FAA.

Length short, data completeness good, site continuity good. Appears to
be a potentially excellent record from 1951-1990; data complete after 1944.
